They were also located in a layer that lacked guano deposits, ruling out spontaneous combustion as an explanation.

Their collective body heat raises the cave’s temperature to a sweltering 106°F, and the piles of guano beneath them are deep enough to bury the Statue of Liberty to her waist.

Their guano, or dung, can also be used as fertilizer.

But, like all farmers, he had to contend with high taxes, high freight rates, and land so worn out that he might spend more for guano than he could get for his cotton crop.

The only way in which adulteration can with certainty be detected, and the value of different guanos be determined, is by analysis, and the importance of this can easily be illustrated.

There is no doubt, however, that such guanos are very useful, and if obtained in large quantity, and of uniform composition, would be used to a much larger extent than they at present are.

In the old rich Peruvian guanos, as we have above shown, the nitrogen was more abundant than is the case at present.
